T-mobile.com is running an 8 day sale that includes some pretty nice deals. The sale is on now until April 19th. The main attraction is free $50 refills with the purchase of most Android phones. But there are some deals on mobile broadband devices too. Here's the full list

The best deal is probably the Samsung Exhibit II 4G pictured above for $225.00. This is one of T-Mobile's best prepaid phones with a 1 Ghz processor, 3.7" 480 X 800 (WVGA) screen. It's also one of the few Android phones with 3G and 14.4 Mbps 4G support for both T-Mobile's Band IV(1700/2100) and AT&T's Band II (1900) and Band V(850). Of course, the phone has to be unlocked to use on AT&T, but T-Mobile will unlock phones for prepaid customers.

Both Amazon and Walmart.com sell the Exhibit II for about $200. But the addition of the free $50 refill, which can be used to fund any T-Mobile prepaid plan makes this an even better deal.
